9.1 Description
Haloperidol is a butyrophenone with a long duration of action. It has lile α- adrenoceptor blocking activity and minimal effect on the cardiovascular system. It is an effective antiemetic but has a high incidence of extrapyramidal adverse effects. Haloperidol may be used in the short-term management of the acutely agitated patient (when sinister causes of confusion such as hypoxaemia and sepsis have been excluded) and in the management of delirium in ICU. The duration of action of haloperidol is approximately 24–48h.
9.2 Chemical Properties
White Crystalline Powder
9.3 Originator

It effectively stops various types of psychomotor excitement. It is used for schizophrenic psychoses, manic, paranoid, and delirious conditions, depression, psychomotor excitement of various origins, and for delirium and hallucinations of different origin.
9.5 Uses
Haloperidol has been used:
  • in ethanol to serves as an inhibitor of Erg2p
  • to address the mechanism of haloperidol in ferroptosis using hepatocellular carcinoma cells: Hep G2 and Huh-7 cell lines
  • in receptor internalization assay
  • as an antipsychotic drug in Dulbecco′s Modified Eagle medium
